New American research shows that there could be a link between the controversial MMR triple vaccine and autism and bowel disease in children.
The study appears to confirm the findings of British doctor Andrew Wakefield, who caused a storm in 1998 by suggesting a possible link.
Now a team from the Wake Forest University School of Medicine in North Carolina are examining 275 children with regressive autism and bowel disease - and of the 82 tested so far, 70 prove positive for the measles virus.
This is the second independent study to back up Dr Wakefield. In 2001 John O'Leary, Professor of Pathology at St James's Hospital and Trinity College, Dublin, replicated his findings.
